Dioxins are among the most toxic chemicals on the earth. They are by-products of a number of human activities such as combustion of fuels and wastes containing polyvinyl chloride (PVC), chlorine bleaching of paper products, and selected industrial processes. Current releases of dioxins by humans are due to the combustion of fuels and burning of household trash. The good news is that levels of dioxins in the environment have decreased in the United States throughout the past 30 years due to the improved emission controls and regulatory activities. But dioxins break down slowly, so they remain in the environment for a long time and accumulate in the food chain. Long-term exposure to dioxins can harm immune system, nervous system, endocrine system, and reproductive functions. This 7-page fact sheet discusses the sources, emission trends, and impacts of dioxins as well as the ways to minimize exposure to dioxins. Written by Yun-Ya Yang and Gurpal S. Toor, and published by the UF Department of Soil and Water Science, July 2015.
Strawberries grown in Florida are attacked by several pests, including flower thrips. Western flower thrips and common blossom thrips (both invasive) can cause damage to strawberries in Florida; but, while the native Florida flower thrips is commonly found in strawberry blossoms, it hasn’t been established that it can cause economic damage to strawberry. This 9-page fact sheet describes thrips damage, characteristics to distinguish among the three species, and methods of control. Written by Jeff D. Cluever, Hugh A. Smith, Joe E. Funderburk, and Galen Frantz, and published by the UF Department of Entomology and Nematology, January 2015. (Photo: H. A. Smith)
Bs2 tomatoes are transgenic tomatoes that have been engineered to contain the Bs2 gene from pepper. As such, they are considered a genetically modified (GM) food, or a genetically modified organism (GMO). Numerous trials conducted by University of Florida researchers have shown the benefits of these cultivars for bacterial spot disease management, and growers and industry members recognize the potential for Bs2 tomatoes to make Florida tomato production more sustainable. This 4-page fact sheet discusses the benefits that might be realized by the adoption of Bs2 tomato varieties, and the challenges standing in the way of their commercial production. Written by S. F. Hutton, J. W. Scott, J. B. Jones, R. E. Stall, G. E. Vallad, B. J. Staskawicz, and D. M. Horvath , and published by the UF Department of Horticultural Sciences, April 2015.
One of many species of thrips found in Florida, Frankliniella occidentalis is a pest of several crops throughout Florida and the world, causing injury by feeding and by transmission of plant viruses.

Urban trees provide shade and beauty and the urban forest as a whole provides a wealth of benefits to neighborhoods and residents. But stresses from the urban environment may lead to problems that pose an unacceptable safety risk to people and property. It is a landowner’s responsibility to ensure that the trees on their property are safe. A key step in reducing the potential for tree-related injury or property damage is learning to identify common tree defects associated with increased risk of failure. This 5-page fact sheet highlights seven easily reconizable tree defects that homeowners and non-professionals in public agencies. may encounter in Florida. Written by Drew C. McLean, Andrew K. Koeser, Robert J. Northrop, and Gitta Hasing, and published by the UF Department of Environmental Horticulture, October 2014. (Photo by Gitta Hasing)

Purslane occurs throughout the year in Florida. It produces thousands of seeds per plant, which germinate readily, but can also persist in the soil for up to 15 years. Vegetative shoot fragments can survive on the soil surface for extended periods of time, then re-root when exposed to moisture and can even flower and produce seeds after they have been pulled from the soil. This characteristic enables purslane to persist and spread following cultivation. This 4-page fact sheet was written by Nathan S. Boyd, Andrew W. MacRae, Rick Kelly, and Ixchel M. Hernandez, and published by the UF Department of Horticultural Sciences, July 2014.
